ABSTRACT
Mapp v. Ohio is another of the long list of landmark cases decided by the Warren Court. In its ruling, the Supreme Court established precedents expanding the Exclusionary Rule and in tying the states to this new standard through the incorporation doctrine. The Court received tremendous criticism because, the critics argued, it would make law enforcement officers follow much tougher guidelines when conducting investigations. Critics argued that criminals would go free because of clerical or superficial errors made by police. Mapp appealed to the US Supreme Court, which ruled that both the Fourth and Fourteenth Amendments applied to this case. The Fourth Amendment guarantees an individual’s protection from unreasonable searches and seizures from the federal government.
